BOTTLE-CAPPIN G MACHINE.

Application filed July 3,1914, Serial No. 848,828.

To all whom it may concern:

Be it known that I, ALBRECHT JoRN, a citizen of the U ited States, residing at North Chicago, in the county of Lake and State of Illinois, have invented a new and useful Bottle-Capping Machine, of which the following is a specification.

The present invention relates to improvements in bottle capping machines, and more particularly to that type of machine used for placing disk caps in milk bottles and the like, one object of the invention being the provision of a plunger actuated means for disposing the cap within the bottle, said means also being provided with means for actuating the cap feeding mechanism so as to insure a proper consonant action between the parts.

A further object of the present invention is the provision of a cap delivering means in which the cap is engaged at opposite sides of the center line thereof and delivered into the directing portion of the machine without injuring the cap.

A still further object of the present invention is the provision of a reciprocating cap delivering plunger in combination with reciprocating or delivering means operating at a plane at right angles to the capping plunger, a bell crank lever being operatively connected to the cap delivering means and in the path of the plunger carrying means so that the cap will be properly delivered and the delivering mechanism receded t0 the next position for the delivery of the next cap.

\Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made with in the scope of what is claimed without departing from the spirit of the invention.

In the drawings: Figure 1 is a front elevation of the complete device, the plunger being in its uppermost position. Fig. 2 is a side elevation thereof taken from the cap delivering mechanism side thereof. Fig. 3 is a view similar to Fig. 2 showing the delivering mechanism in its retracted position with the plunger delivering cap. Fig. 1 is a section taken on the line 44: of Fig. 2. Fig. 5 is a vertical central sectional View Specification of Letters Patent.

taken longitudinally of the cap delivering and guiding member. Fig. 6 is a section taken on the line 6-6 of F ig. 3. Fig. 7 is a perspective view of the cap delivering member per se. 7

Referring to the drawings, the numeral 1 designates the main frame of the machine which is provided with the cap magazine 2 having a pair of lower forward lugs or ears 3 secured by means of screws 4: upon the annular member or head 5. Said magazine 2 also has a lower rear ear or lug 7 fastened by means of a screw 8 upon the guiding member 6 of the cap delivery mechanism as will presently appear. The lugs 3 and 7 support the magazine above the member 5 and its outstanding guide 6. The annular member 5 constitutes the cap receptacle for guiding the same to the mouth of the bottle (not shown) andis provided with the reduced cylindrical end 9 as shown in Fig. 5 which is connected to the bottle receiving member 10 which is connected to the reduced end 9 by means of the screw 11.

As shown in Fig. 5, the upper end of the member 5 for the reception of the bottle cap (not shown) is enlarged as at b, so that the cap when forced through the member 5 into the mouth of the bottle will tightly impinge the sides of the annular member 5 and cannot be accidentally displaced. A guiding ing 12 is attached to the forward end of the member 5 above the rim 6.

Formed integral with the supporting frame 1 and projecting from its front face thereof are the lugs 13 and 14 which are apertured to receive the reciprocatory rod 15 carrying the cap delivering plunger 16 upon the lower end, while attached to the upper end is a casting 17 having the upstanding member 18 to which is connected through the rod 19 the operating handle 20. Thus the plunger 16 ismanually reciprocated to move the same into and out of the annular member 5.

An adjustable pin 21 is mounted within the casting 17 at one side of and parallel to the rod 15, there being provided the adjusting nut 22 to regulate the vertical adjustment of the pin' 21, the purp'ose'of which will presently appear. Also carried bythe casting 17 and interposed between the rod 15 and the pin 21 and parallel therewith is a rod 23, the same being of greater length than the pin 21 and having adjustably mounted thereupon the lug or stop 25 by means of the screw The purpose'of this will be described hereinafter.

Formed integral with the supporting structure 1 at one side thereof and at its rear is a boss 26 which carries the journaling pin. 27, the sleeve 28 of the bell crank lever 29 being jcurnaled thereon for oscillatory movement. The terminal .30 of the bell crank lever carries a pin 31 which has journaled thereon a roller 32, the same being disposed in. the path to be engaged alternately by the pin 21 as the plunger 16 descends and by the lug 25 when the plunger 16 ascends. By this means, the desired oscillatory movement is imparted to the bell crank lever 29 so that the cap feeding member 38 will be properly reciprocated upon the dovetail-shaped guide 6. The terminal of the bell crank lever 29 also forms a handle so that the same may be operated manually in adjusting the pin and lug 25 to secure the proper t'ain of action between the parts.

In the terminal 38 of the bell crank lever 29 is mounted a pin 34 the same being threaded therein and having its cylindrical portion connected to one end of the link 35, whose other end is connected to the pin 36 between the two spaced lugs 37 carried by the cap delivering member 38. This member 38 has upstanding sides which lit the sides of the guide 6 and have their forward ends as at a cutaway to conform to the curvature of the rim of the cap, the upper edges thereof being projected above the up per surface of the guide so that the lowermost cap within the receptacle 2 will be delivered through the outlet 0 into the recess Z) of the member 5. The upper edge of the member 38 engages only a small portion of the lowermost cap within the receptacle 2 to maintain the same in any desired position. above the guide 6 until the parts are in the position shown in Fig. 3 at which time the lowermost cap rests upon the upper surface of the guide 6 to be delivered forwardly into the plunger receptacle when the parts assume the positions shown in Figs. 1 and 2. The guide 6 is of inverted T-shaped cross secticn to provide outstanding flanges, and the sides of the cap delivering member 38 seat slidably upon said flanges, whereby the cap delivering member will move or reciprccate properly along the guide. Thus it will be seen that when the plunger is de pressed, that the bell crank lever will be operated to retract the member 38 to assome the position shown in Fig. 3, and when the same is elevated to the positions shown in Figs. 1 and 2, the bell crank lever will be operated to deliver a cap and place the same upon the recess Z) of the cap guiding means or sleeve 5. Carried in the terminal 33 of the bell crank lever is an adjusting screw 39, which is adapted to co'iperate with the lug 40 of the member 5 to limit the inward swing of the same as illustrated in Fig. 2.

From the foregoing description, it will be evident that the present apparatus is readily cleaned, therefore producing a sanitary de vice, and further in view of the fact that the frame or supporting structure 1 is open in the rear the caps are at all times visible, and that a defective cap can be readily detected and removed.

By providing the two-point contact for engaging the cap for delivery to plunger receivmg position, the edges of the cap are not injured as would be the case where a solid plunger is employed, and at the same time, the next succeeding cap is held. above the guide until the delivery mechanism is in its full retracted position. By producing a two-point contact for the cap, the cap at all times is properly centered so that it is delivered in a proper alined plunger receiving position upon the elevation of the plunger mechanism.

hat is claimed is A bottle capping machine embodying anannular capping head provided with an outstanding guide of inverted T-shaped cross section to provide outstanding flanges, a magazine having a lower ear secured upon said guide and a pair of lower ears secured upon said head, said ears supporting the magazine above the guide and head, and a reciprocatory cap delivering member having upstanding sides fitting the sides of said guide and seating upon said flanges, the

upper edges of'the sides of said cap deliver I mg member projecting above the guideto move underthe magazine for carrying a cap therefrom over the head, certainends of said upstanding sides of the cap delivering member being so formed as to engage the caps.

In testimony that I claim the foregoing as my own, I have hereto atlixed my signature in the presence of two witnesses.
